[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a ventilation device for a massage chair cushion 202, comprising a ventilation device body 2 mounted on the main frame 1 of the massage chair, the ventilation device body 2 including a fan 201 and a cushion 202, the upper surface of the cushion 202 having ventilation holes 3, and the lower surface of the cushion 202 having a connecting opening 4, the fan 201 being mounted on the main frame 1 of the massage chair with its air outlet connected to the connecting opening 4 of the cushion 202, a sponge layer 5 and a non-mesh fabric layer (not shown in the figure) being provided between the upper and lower surfaces of the cushion 202, both the sponge layer 5 and the non-mesh fabric layer having breathable holes, the surface of the cushion 202 being made of non-breathable leather material, and the non-mesh fabric layer being sewn... The inner side of the seat cushion 202, which is made of leather, is provided with a sponge layer 5 consisting of a mesh sponge layer 502 with a certain density of breathable holes, a molded sponge layer 501, and another mesh sponge layer 502 from top to bottom. The mesh sponge layer 502, the molded sponge layer 501, and the mesh sponge layer 502 can provide the seat cushion 202 with a certain support and anti-deformation effect, as well as good ventilation performance. For ventilation, fans 201 can be installed on both sides of the seat cushion 202. The fans 201 can be powered by an external power source through a power cord. The massage chair frame 1 is provided with a slot 17 for placing the fans 201 to ensure the comfort of the user when sitting.

[0025] Specifically, the seat cushion 202 is U-shaped and positioned in the seat area of ​​the massage chair. This avoids the seat cushion 202 being positioned in the exact center of the seat, which would deform too much when the user sits down and thus fail to provide a good air blowing effect.

[0026] Specifically, the bottom layer of the seat cushion 202 is provided with an outer U-shaped frame 7 and an inner U-shaped frame 8. The outer U-shaped frame 7 is fixed to the main body frame 1 of the massage chair, and the inner U-shaped frame 8 is rotatably mounted on the outer U-shaped frame 7. Multiple sets of deformation limiting components 9 are connected between the outer U-shaped frame 7 and the inner U-shaped frame 8, forming a U-shaped area 18 between the outer U-shaped frame 7 and the inner U-shaped frame 8. The deformation limiting components 9 are evenly distributed along the path of the U-shaped area 18. Rotating rods 19 are rotatably mounted on both sides of the inner U-shaped frame 8. The outer ends of the rotating rods 19 are inserted into the outer U-shaped frame 7 and form a rotatable connection. The inner U-shaped frame 8 is rotatably connected to the outer U-shaped frame 7 through the rotating rods 19. The deformation limiting components 9 can limit the amount of deformation at the seat when the user sits down. This design ensures that the seat returns to its initial shape after each massage, extending its lifespan. The outer U-shaped frame 7 can be fixed to the main frame 1 of the massage chair by welding or bolts. It should be noted that the outer U-shaped frame 7 and the inner U-shaped frame 8 are made of hard alloy steel. The seat cushion 202 is manufactured in combination with the outer U-shaped frame 7 and the inner U-shaped frame 8. Alternatively, it can be made by adding a layer of leather to cover the inner U-shaped frame 8 and the outer U-shaped frame 7 and then sewing them together. When using this method, the leather seat cushion 202 between the inner U-shaped frame 8 and the outer U-shaped frame 7 needs to have some slack to avoid the seat cushion 202 interfering with the rotation of the inner U-shaped frame 8 and the outer U-shaped frame 7.

[0027] Specifically, the deformation limiting assembly 9 includes an elastic support rod 901, a first ball 902, a second ball 903, and an intermediate limiting part 904. The first ball 902 is rotatably mounted on the outer U-shaped frame 7 and has a first pressure sleeve 10 extending towards the second ball 903. The second ball 903 is rotatably mounted on the inner U-shaped frame 8 and has a second pressure sleeve 11 facing the first ball 902. Both the first ball 902 and the second ball 903 have a connecting hole 16 through which the elastic support rod 901 passes. One end of the elastic support rod 901 passes through the connecting hole 16 of the first ball 902 and is fixed to the outer U-shaped frame 7. The other end of the elastic support rod 901 passes through the connecting hole 16 of the second ball 903. And fixed to the inner U-shaped frame 8, the elastic support rod 901 can be made of spring steel, which has sufficient support and recovery effect after deformation. The diameter of the elastic support rod 901 can be selected according to the support effect, and the elastic support rod 901 is column-shaped. In addition, the outer U-shaped frame 7 is provided with a ball groove 15 for the first ball 902 to rotate, and the inner U-shaped frame 8 is also provided with a ball groove 15 for the second ball 903 to rotate. More than half of the first ball 902 and the second ball 903 are located inside the ball groove 15. When the user sits down, it will drive the inner U-shaped frame 8 to rotate downward and drive the elastic support rod 901 to deform, preventing the user's buttocks from sinking into the massage chair seat; the first pressure sleeve 10 and The inner annular side of the second pressure sleeve 11 is provided with a first annular inclined surface 12 for abutting against the intermediate limiting part 904; the intermediate limiting part 904 includes a third sphere 9041 and a third pressure sleeve 9042 disposed on the intermediate sphere. The two ends of the third pressure sleeve 9042 extend axially into the interior of the first pressure sleeve 10 and the second pressure sleeve 11, respectively. The first pressure sleeve 10 and the second pressure sleeve 11 have the same diameter, and the diameter of the inner annular side is larger than the diameter of the outer annular side of the third pressure sleeve 9042. After the two ends of the third pressure sleeve 9042 extend into the first pressure sleeve 10 and the second pressure sleeve 11, they have gaps with the inner walls of the first pressure sleeve 10 and the second pressure sleeve 11, respectively. In addition, if the user's weight is too large, it is necessary to prevent the elastic support rod 901 from deforming. If the deformation is too large, the deformation of the elastic support rod 901 will cause the first ball 902 and the second ball 903 to rotate. After the elastic support rod 901 deforms to a certain extent, the rotation of the first ball 902 and the second ball 903 will cause the first pressure sleeve 10 and the second pressure sleeve 11 to abut against the third pressure sleeve 9042, thereby limiting the continued deformation of the elastic support rod 901. It should be noted that when the elastic support rod 901 deforms to the critical state of limiting deformation, the upper and lower outer walls of one axial end of the third pressure sleeve 9042 abut against the upper and lower inner walls of the inner ring of the first pressure sleeve 10, and the upper and lower outer walls of the other axial end of the third pressure sleeve 9042 abut against the upper and lower inner walls of the inner ring of the second pressure sleeve 11.

[0028] Specifically, a fourth sphere 14 is provided in the middle of the elastic support rod 901, and a ball groove 15 for the fourth sphere 14 to rotate is provided in the middle of the third sphere 9041. A through hole 20 is provided through the third sphere 9041, and the through hole 20 is coaxially arranged with the hollow part of the third pressure sleeve 9042. The diameter of the through hole 20 is larger than the diameter of the elastic support rod 901, so that the elastic support rod 901 has a certain space for deformation. The third sphere 9041 is provided, and the ball groove 15 for the fourth sphere 14 to rotate is provided inside the third sphere 9041, so that the third sphere 9041 and the fourth sphere 14 can have a certain amount of relative rotation when the elastic support rod 901 deforms.

[0029] A specific application example of this embodiment is as follows:

[0030] When the user sits on the massage chair, the weight of the user will cause the inner U-shaped frame 8 to rotate downwards. The downward rotation of the inner U-shaped frame 8 will cause the elastic support rod 901 to deform, preventing the user's buttocks from sinking too much and improving comfort.

[0031] When the user's weight is too great, in order to limit the deformation of the elastic support rod 901, when the elastic support rod 901 deforms downward to a certain extent, the first ball 902 and the second ball 903 will rotate under the action of the downward deformation of the elastic support rod 901. The rotation of the first ball 902 and the second ball 903 will cause the first inclined surface on the inner side of the first pressure sleeve 10 and the second pressure sleeve 11 to abut against the upper and lower inner walls of the upper inner ring of the third pressure sleeve 9042, thereby limiting the elastic support rod 901 from continuing to deform downward.

[0032] After the deformation limiting component 9 supports the human body, if the user feels stuffy during massage, the power supply of the ventilation fan 201 can be connected. The fan 201 blows air into the seat cushion 202 and through the sponge layer 5, the non-mesh fabric layer and the ventilation holes 3 of the upper deformation layer of the seat cushion 202 to cool down the buttocks area. Under the action of the deformation limiting component 9, the sponge layer 5 and the non-mesh fabric layer will not deform too much, ensuring smooth ventilation.
